indeed. I've fixed it for the console window. At other places (notably the 
command log window), it's still handled incorrectly, though.

Interestingly, I do not see this issue, any more. However, it was a different 
beast to start with, originating in a buggy handling of "slow" output in 
kdesu.

Do you see this only when installing as root, or all the time? In the first 
case, conceivably Ubuntu's kdesu-replacement (kdesudo) has the same bug that 
kdesu used to have. Try this in a bash session:

   /usr/lib/kde4/libexec/kdesu -t sh -c 'for i in {1..10}; do echo -n $i;
      sleep .5; done'

(there should be no line breaks between the numbers).

Regards
Thomas
